Abstract

The propylene polymer composition of the invention comprises, as its essential components, a specific propylene polymer [A] described below and a propylene block copolymer [B]. In addition to the propylene polymer [A]
and the propylene block copolymer [A], the propylene polymer composition may contain a thermoplastic elastomer [C] selected from polystyrene polyethylene/poybutylene polystyrene block copolymers and ethylene/.alpha.-olefin random copolymers, or may further contain an inorganic filler [D].
The propylene polymer [A] used in the invention has the following characteristic properties:
(1) a boiling heptane-insoluble component is contained in said polymer in an amount of not less than 96 % by weight, (2) a pentad isotacticity [M5] of the boiling heptane-insoluble component obtained from the following formula (1) using a 13C-NMR spectrum is in the range of 0.970 to 0.995:
(3) a pentad tac-ticity [M3] of the boiling heptane-insoluble component obtained from the following formula (2) using a 13C-NMR spectrum is in the range of 0.0020 to 0.0050:

and (4) a melt flow rate (MFR) of said polymer is in the range of 5 to 50 g/10 min.
The propylene polymer compositions of the invention are excellent in both of rigidity and impact strength.
